Abstract: The control of Aedes aegypti with 1% granulated formulation of temephos has been widely used in field control programmes in Brazil. The impact of temephos application was evaluated in Americana São Paulo, where an Aedes control programme was in place since 1991. Two areas with similar conditions of Aedes infestivity were selected. In the experimental area, temephos application 1 ppm at a frequency of three-month intervals and source reduction by communities were the methods used for control, whereas in the control area only source reduction was attemped. Monthly surveillance of larval population was undertaken using the larval indicies, viz. Breteau Index (BI), Container Index (CI), and identification of Aedes aegypti types of breeding sites. Trends were also observed in relation to rainfall and minimum temperature. A covariance test was performed to compare the two different areas. Results indicated that the area subjected to temephos application presented similar levels of Aedes aegypti larval infestation as the untreated area. The larval infestation varied with the degree of rainfall but not with temperature. Positive breeding sites for Aedes aegypti more frequently encountered were plant vases, tanks and drums in the experimental area. A comprehensive operational research study is required to determine the causes of failure of temephos to suppress the Aedes aegypti population under an operational programme.
